From
The first program should input the name of the drink and the number of milligrams of caffeine in the drink. It should then output the drink name and the number of drinks it takes to kill a person. For example, if the user enters "coffee" and "160", then the program should output "It will take approximately 62.5 drinks of coffee to kill a person from caffeine."
The second program should perform the same calculation as the first program, but read the name of the drink and the number of milligrams of caffeine in the drink from a file named drink. txt and output the answer to the console.

Write a program with total change amount (in cents) as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies.
Hint: Start from the largest denomination. Divide the change amount by the number of cents in the denomination to get the number of coins used. The remainder of the division is used to find the number of coins used in the next denomination. Ex: value // 100 gives the number of dollars used. The remainder is divided by 25 to find the number of quarters used.
Ex: If the input is:
0
(or less than 0), the output is:
No change
Ex: If the input is:
45
the output is:
1 Quarter 2 Dimes

Write a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is:
Between $0 and $15,000, the tax rate is 15%.
Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000.
Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information:
Marital status
If the marital status is “married,” ask for the number of children under the age of 14
Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.)
Percentage of gross income contributed to a pension fund Your program must consist of at least the following functions:

- Write a program that reads the amount of a monthly mortgage payment andthe amount still owed—the outstanding balance—and then displays theamount of the payment that goes to interest and the amount that goes toprincipal (i.e., the amount that goes to reducing the debt).
